Update 11 Feb 2020: Toxic algae update for greater Wellington region

Unfortunately two dogs died recently after eating detached toxic algae mats along the Waipoua River. The dog deaths re-inforce the importance of Greater Wellington's summer monitoring programme and the role we play in keeping our communities, and their pets, safe.

Current no swim warnings

  • Waipoua River, warning extends from Paierau Road to confluence with the Ruamahanga.

Caution advised warnings

  • Waikanae River, warning extends from Main Rd (old SH1) to river mouth
  • Hutt River, warnings for Melling and Siverstream sites.
  • Ruamahanga River, warning for Morrison’s bush site.
  • Otaki River, warning extends Hautere Water Treatment Plant to the mouth

Warnings removed

  • Warnings for the Waingawa river have been lifted following recent rain in these catchments.

Key messages for the public

  • We recommend you avoid swimming and keep dogs away from these rivers at this time. The best thing you can do to stay safe is to know what toxic algae looks like and avoid it - watch the video here.
